Call of Duty: Black Ops 2 details have been oozing out of Gamescom. VG247 have details of an updated "build a class" mode that will let us occupy ten gear slots with any combination of weapons, perks and killstreak rewards. Levelling up will mean choosing one of seven new pieces of kit to unlock. If you want to grab the six you missed, you'll have to prestige and reset your character.

You're not restricted to having to occupy certain slots with weapons, and other slots with perks. You can forgo your primary gun in favour of an extra perk, or a "wild card" ability that changes the way your weapon behaves, adding an alternative fire mode or letting you slot an extra attachment onto your weapon. Treyarch refer to the system as "pick 10."

It's not too far off Diablo 3's sideways levelling system that lets you slide any unlocked skill into a limited number of slots. Levelling grants you new tools with which to customise your loadout, which can then be swapped in for another skill whenever you fancy a change. It should introduce a significant element of choice to CoD's levelling system, and bring a bit of chin-stroking build pondering to the lull between Black Ops' frenzied fire fights.

There are more than a hundred kit items and powers to choose from, and VG247 have grabbed a handy list to give us an advanced look at the range of abilities on offer. Given that you'll need to prestige to get hold of all of them, we'll have to shoot a lot of men before we get access to the full weapons locker.
